First Embodiment

Reference is made to FIG. 1 and FIG. 2, in which a first exploded viewand a second exploded view of a digital display according to a firstembodiment of the present disclosure are shown, respectively. The firstembodiment of the present disclosure provides a digital display Zincluding a light unit 1, a display unit 2 and a fixing unit F. Thelight unit 1 has a front 10 as a light emitting surface and a rear 11opposite to the front 10 as an electrical connection part. The displayunit 2 has a display surface 20 corresponding to the front 10. Thefixing unit F is used to hold the display unit 2 upright on an externalsubstrate S.

Specifically, as shown in FIG. 1, the digital display Z of the presentdisclosure includes the light unit 1, the display unit 2 and the fixingunit F. The light unit 1 can be a substrate with a plurality ofoptoelectronics (such as a light emitting diode (LED) device includingLED chip and LED package). The front 10 of the light unit 1 can beconnected to the display unit 2. The display unit 2 cooperates with alight beam generated by the front 10 of the light unit 1 to displaydigits, text, symbols and graphics on the display surface 20. The fixingunit F can be disposed at a bottom of the display unit 2. Accordingly,the digital display Z of the present disclosure can be connected to theexternal substrate S by the fixing unit F, so that the fixing unit F canhold the display unit 2 upright on the external substrate S. Inaddition, the light unit 1 can also be electrically connected to theexternal substrate S. The external substrate S can be a circuit board,but is not limited thereto.

Further, the display unit 2 has a plurality of display windows 20a thatare hollow through the front 10 to the display surface 20, and thedisplay windows 20 a cooperate to form the displayed digits, text,symbols and graphics. In addition, the display unit 2 can include areflective member and a print tape pasted onto the reflective member,wherein the print tape has a plurality of light transmissive segmentsthat can be formed as the plurality of display windows 20 a. The lightunit 1 can include a plurality of optoelectronics 10 a corresponding toeach of the display windows 20 a and a circuit substrate 10 b, and theplurality of optoelectronics 10 a can be disposed on the front 10 of thecircuit substrate 10 b. In the present embodiment, the digital display Zof the present disclosure has two numbers, each of which has eightdisplay windows 20 a. Seven of the display windows 20 a form an “8”shaped display character, and another one of the display windows 20 a isa decimal point display character at a lower right corner of the “8”shaped display character, but the present disclosure is not limitedthereto.

In an exemplary embodiment, the display unit 2 and the fixing unit F ofthe present disclosure can be an integrated component. For example, thefixing unit F can be made of metal or plastic, and the fixing unit F canbe made in advance. Then, during the process of forming the display unit2, a part of the fixing unit F is placed into the display unit 2. Afterthe display unit 2 is formed, the display unit 2 and the fixing unit Fcan be a single, integral component.

Further, the fixing unit F can include a plurality of first fixing partsF10 and at least one supporting part F11 correspondingly embedded in thedisplay unit 2, and the plurality of first fixing parts F10 are exposedoutside the display unit 2. The fixing unit F can have a U-shape or aW-shape structure, and the supporting part F11 connects the two adjacentfirst fixing parts F10.

For example, as shown in FIG. 1, the U-shaped structure of the fixingunit F can be formed by connecting one supporting part F11 to the twoadjacent first fixing parts F10. In addition, the supporting part F11can be embedded in the display unit 2, and the two adjacent first fixingparts F10 are exposed outside the display unit 2. The first fixing partF10 can have a columnar structure. Accordingly, the fixing unit F can beinserted into the external substrate S through the first fixing part F10to hold the display unit 2 upright on the external substrate S. That is,the display unit 2 is fixed to the external substrate S and isperpendicular to the external substrate S (also as shown in FIG. 7).

As shown in FIG. 2, the W-shaped structure of the fixing unit F can alsobe formed by connecting a plurality of the supporting parts F11 to theplurality of first fixing parts F10. For example, the two first fixingparts F10 are connected to the same supporting part F11 at theiradjacent ends, and another end of each of the two first fixing parts F10is connected to each of another two supporting parts F11, but is notlimited thereto. Moreover, the supporting parts F 11 can also beembedded in the display unit 2, and the plurality of first fixing partsF10 are exposed outside the display unit 2. The first fixing part F10can have a columnar structure. Accordingly, the fixing unit F can beadhered to the external substrate S through the first fixing part F10 incombination with solder paste or other adhesives, so as to hold thedisplay unit 2 upright on the external substrate S.

Accordingly, the digital display Z of the present disclosure can notonly be disposed on the external substrate S in an upright mannerthrough the abovementioned technical solution, but can also be disposedon the external substrate S together with other electronic components byusing a surface mount technology (SMT) process without the need for aseparate SMT process.

In addition, the bottom of the display unit 2 protrudes outward to format least one first positioning part 21. Accordingly, when the digitaldisplay Z of the present disclosure is fixed on the external substrate Sthrough the fixing unit F, in addition to using the first positioningpart 21 to achieve the function of limiting a distance between thedisplay unit 2 and the external substrate S, the display unit 2 can alsobe firmly held by the first positioning part 21 abutting against theexternal substrate S, so that the display unit 2 can be firmly heldupright on the external substrate S. With respect to the externalsubstrate S, protrusion heights of the first positioning part 21, thefirst fixing part F10 of the fixing unit F, and the substrate of thelight unit 1 are preferably equal, thereby providing a more stablesupporting structure.

However, the aforementioned example is merely one of the feasibleembodiments, and is not meant to limit the scope of the presentdisclosure.

Second Embodiment

Referring to FIG. 3, which is to be read in conjunction with FIG. 1 andFIG. 2, a partly exploded view of a digital display according to asecond embodiment of the present disclosure is shown. As shown in thefigures, the digital display Z in the present embodiment issubstantially similar to the digital display Z in the first embodimentdescribed above, and will not be repeated herein. The difference betweenthe present embodiment and the first embodiment described above is thatin the present embodiment, the fixing unit F can include a plurality ofsupporting members F2. One end of each of the supporting members F2 isconnected to the display unit 2, and the other end of each of thesupporting members F2 is exposed outside the display unit 2.

For example, the fixing unit F of the present disclosure can include aplurality of supporting members F2. Each of the supporting members F2has a main body part F20 and a second fixing part F21 connected to themain body part F20. The main body part F20 can be embedded in thedisplay unit 2, and the second fixing part F21 can be exposed outsidethe display unit 2. The supporting member F2 can be similar to thestructural design of a headpin, but is not limited thereto. Accordingly,the digital display Z in the present embodiment can be adhered to theexternal substrate S through the second fixing part F21 of each of thesupporting members F2 in cooperation with solder paste or otheradhesives, so as to hold the display unit 2 upright on the externalsubstrate S. Moreover, the light unit 1 can also be electricallyconnected to the external substrate S.

It is worth noting that the plurality of supporting members F2 and thedisplay unit 2 of the present disclosure can form a single, integralcomponent (being made in the manner described in the first embodiment)or can be independent components. In an embodiment in which theplurality of supporting members F2 and the display unit 2 areindependent components, the plurality of supporting members F2 can beengaged with each other by snap-fixing, screwing, or other joiningmethods.

Further, when the digital display Z of the present disclosure is fixedto the external substrate S by the second fixing part F21 of the fixingunit F, the display unit 2 can also be firmly held upright on theexternal substrate S by the first positioning part 21 of the displayunit 2 abutting against the external substrate S.

However, the aforementioned example is merely one of the feasibleembodiments, and is not meant to limit the scope of the presentdisclosure.

Third Embodiment

Referring to FIG. 4 and FIG. 5, which are to be read in conjunction withFIG. 1 to FIG. 3, a perspective view and a side view of a digitaldisplay according to a third embodiment of the present disclosure areshown, respectively. As shown in the figures, the digital display Z inthe present embodiment is substantially similar to those in theembodiments described above, and will not be repeated herein. Thedifference between the present embodiment and the embodiments describedabove is that in the present embodiment, the light unit 1 has a rear 11opposite to the front 10 and a plurality of terminals 12 correspondinglyconnected to the rear 11.

For example, as shown in FIG. 4 and FIG. 5, the light unit 1 in thepresent embodiment has the front 10 and the rear 11 opposite to thefront 10, and the plurality of terminals 12 as a pin array are connectedto the rear 11 of the light unit 1. Therefore, the light unit 1 can beelectrically connected to the external substrate S through the pluralityof terminals 12 (also as shown in FIG. 7).

Further, the fixing unit F can include a positioning member F3, which isconnected to the rear 11 and corresponds to a bottom of the light unit1. In addition, one end of each of the terminals 12 passes through thepositioning member F3 at an equal interval and on the same horizontalplane, and is connected to the rear 11. The one end and another end ofeach of the terminals 12 are arranged in a staggered manner and parallelto each other. There can be ten terminals 12, but is not limitedthereto.

For example, as shown in FIG. 4, the fixing unit F of the presentdisclosure can include the positioning member F3, which may have aninverted U-shaped structure. The positioning member F3 has a bottomsurface F30 that is perpendicular to and away from the rear 11, and aconcave part F31 is formed by an inward depression of the bottom surfaceF30. Each of the terminals 12 has a front end part 120, a rear end part121 and a mid-end part 122. The mid-end part 122 is correspondinglyconnected to the front end part 120 and the rear end part 121. The frontend part 120 passes through the positioning member F3 and is connectedto the rear 11. The front end part 120 and the rear end part 121 arearranged in a staggered manner and parallel to each other. The mid-endpart 122 is inclined relative to the front end part 120 and the rear endpart 121. In addition, a contact 1210 of the rear end part 121 incontact with the external substrate S is parallel to and coplanar withthe bottom surface F30.

Accordingly, when the digital display Z is disposed on the externalsubstrate S, it can be connected to the external substrate S through thebottom surface F30 of the positioning member F3 and the rear end part121 of the terminal 12 of the light unit 1, so that the display unit 2can be held upright on the external substrate S. The bottom surface F30and the rear end part 121 can be fixed on the external substrate S byusing solder paste or other adhesives.

However, the aforementioned example is merely one of the feasibleembodiments, and is not meant to limit the scope of the presentdisclosure.

Fourth Embodiment

Referring to FIG. 6 and FIG. 7, which are to be read in conjunction withFIG. 1 to FIG. 5, an exploded view and a side view of a digital displayaccording to a fourth embodiment of the present disclosure are shown,respectively. As shown in the figures, the digital display Z in thepresent embodiment is substantially similar to the digital display Z inthe third embodiment described above, and will not be repeated herein.The difference between the present embodiment and the third embodimentdescribed above is that in the present embodiment, the fixing unit Fincludes a shield member F4 of a window F40. The light unit 1 and thedisplay unit 2 are arranged inside the shield member F4, and the displaysurface 20 of the display unit 2 corresponds to the window F40.

For example, as shown in FIG. 5 and FIG. 6, the fixing unit F of thepresent disclosure can include the shield member F4, which can be hollowand have the window F40 communicating between the exterior and theinterior on its front side surface. The interior of the shield member F4can accommodate the light unit 1, the display unit 2 and the positioningmember F3, and the window F40 is adjacent to and corresponds to thedisplay surface 20. Accordingly, the digital display Z of the presentdisclosure can be shielded from an external electromagnetic interference(EMI) through the shield member F4.

Further, the shield member F4 can include a front part F41, a pluralityof side parts F42, an upper part F43, a lower part F44 and a rear partF45. The front part F41 has the window F40, the front part F41 isarranged opposite to the rear part F45, each end of the plurality ofside parts F42 and the upper part F43 is correspondingly connected tofront part F41 and the rear part F45, and one side of each of the sideparts F42 corresponding to the lower part F44 protrudes outward to format least one third fixing part F420. One end of the lower part F44 isconnected to the front part F41, and at least one matching part F440 isformed by the extension toward the rear part F45 on another end of thelower part F44. The one of the ends of the plurality of side parts F42,the upper part F43 and the lower part F44 connected to the front partF41 correspondingly include at least one elastic element F410.

For example, the shield member F4 of the present disclosure can includethe front part F41, the plurality of side parts F42, the upper part F43,the lower part F44 and the rear part F45, but is not limited thereto.The plurality of side parts F42, the upper part F43 and the lower partF44 are correspondingly connected to the front part F41, and the upperpart F43 is connected to the rear part F45. The plurality of side partsF42 correspond to and are parallel to each other, the upper part F43 andthe lower part F44 correspond to and are parallel to each other, and thefront part F41 and the rear part F45 correspond to and are parallel toeach other, but is not limited thereto.

Accordingly, the digital display Z of the present disclosure can coverthe light unit 1, the display unit 2 and the positioning member F3through the shield member F, and also uses the matching part F440 of thelower part F44 to engage with the concave part F31 of the positioningmember F3, thereby firmly fixing the light unit 1, the display unit 2and the positioning member F3 inside the shield member F4. The bottomsurface F30 of the positioning member F3 is exposed outside the lowerpart F44 of the shield member F4. Then, when being disposed on theexternal substrate S, the digital display Z is erected on a surface Siof the external substrate S through the bottom surface F30 of thepositioning member F3 and the rear end part 121 of the terminals.Further, the third fixing part F420 of each of the side parts F42 can beinserted into the external substrate S to firmly hold the display unit 2upright on the external substrate S. In addition, the digital display Zof the present disclosure can be engaged with an external object, suchas a plate, through the elastic element F410 of the shield member F4, soas to fix a side with the display surface 20 of the digital display Z tothe external object.

However, the aforementioned example is merely one of the feasibleembodiments, and is not meant to limit the scope of the presentdisclosure.

Fifth Embodiment

Referring to FIG. 8 to FIG. 11, which are to be read in conjunction withFIG. 1 to FIG. 7, a side view and a second exploded view of a digitaldisplay according to a fifth embodiment of the present disclosure, aswell as a sectional schematic view of part XI-XI in FIG. 10 are shown,respectively. As shown in the figures, the digital display Z in thepresent embodiment is substantially similar to the digital display Z inthe third embodiment described above, and will not be repeated herein.The difference between the present embodiment and the third embodimentdescribed above is that in the present embodiment, the fixing unit Fincludes a base F50 connected to the display unit 2 and a plurality offixing members F51 connected to the base F50. The base F50 has aplurality of first through holes F500, each of the plurality ofterminals 12 has an L-shaped structure, and each of the plurality ofterminals 12 passes through the corresponding first through holes F500.One end of each of the terminals 12 is connected to the display surface11, and the other end of each of the terminals 12 is connected theexternal substrate S. As shown in FIG. 8 to FIG. 10, the plurality ofterminals 12 can be arranged in upper and lower rows and be connected tothe rear 11, and the plurality of terminals 12 in each row are arrangedon the same horizontal plane and at an equal interval.

For example, as shown in FIG. 8 to FIG. 10, the fixing unit F of thepresent disclosure can include the base F50 and the plurality of fixingmembers F51 in the present embodiment. The base F50 has an upper surfaceF501 and a lower surface F502 corresponding to each other, and each ofthe first through holes F500 is spatially communicated with the uppersurface F501 and the lower surface F502. The light unit 1 and thedisplay unit 2 can be disposed on the upper surface F501 of the baseF50. Each of the terminals 12 of the light unit 1 passes through one ofthe first through holes F500, and the fixing member F51 can be connectedto the lower surface F502 of the base F50.

Accordingly, when the digital display Z is disposed on the externalsubstrate S, the digital display Z can be inserted into the externalsubstrate S through the plurality of fixing members F51 to hold thedisplay unit 2 upright on the external substrate S. In addition, theplurality of terminals 12 can also be used to connect to the externalsubstrate S, such that the digital display Z is electrically connectedto the external substrate S (also shown in FIG. 7).

Further, the lower surface F502 of the base F50 can protrude outward toform a plurality of limiting parts F503. Therefore, the plurality oflimiting parts F503 can limit a distance between the base F50 and theexternal substrate S when the plurality of fixing members F51 areinserted into the external substrate S, and also firmly hold the baseF50 by abutting against the external substrate S after the plurality offixing members F51 are inserted into the external substrate S. In thisway, the display unit 2 can be firmly held upright on the externalsubstrate S by the base F50.

Still further, the base F50 can have at least one second through holeF504, and at least one positioning part 22 is formed by a protrusionoutward on one side of the display unit 2 corresponding to the base F50.

For example, the base F50 of the present disclosure can have at leastone second through hole F504 corresponding to the display unit 2, and abottom surface of the display 2 has a second positioning part 22corresponding to the second through hole F504. Therefore, when thedisplay unit 2 is disposed on the base F50, the display unit 2 can beengaged in the second through hole F504 through the second positioningpart 22 to be accurately positioned on the base F50, so as to prevent ashift in position.

Still further, as shown in FIG. 10 and FIG. 11, the fixing unit F of thepresent disclosure can further include a holder F6 disposed on the baseF50. The holder F6 has a top surface F60 and a bottom surface F61. Inaddition, the holder F6 further has a plurality of grooves F62 arrangedat intervals, and each of the grooves F62 has a first surface F620 and asecond surface F621 that are arranged adjacently and in a staggeredmariner. That is, a ladder structure is formed in each of the groovesF62. A distance h1 between the first surface F620 and the bottom surfaceF61 is smaller than a distance h2 between the second surface F621 andthe bottom surface F61. For example, the holder F6 can also be disposedon the upper surface F501 of the base F50, and the holder F6 has theplurality of grooves F62 that can have the plurality of terminals 12 aand 12 b disposed therein. One part of the terminals 12 a passes throughthe first surface F620, and another part of the terminals 12 b passesthrough the second surface F621. Accordingly, the holder F6 is disposedon the base F50 to firmly fix the plurality of terminals 12 a and 12 b.In other words, the plurality of terminals 12 a and 12 b have a two-rowstructure, and the holder F6 has accommodation spaces for the terminals12 a disposed on the first row and for the terminals 12 b disposed onthe second row, correspondingly. Moreover, the grooves F62 which arearranged at intervals act as limit slots, so that each set of theterminals 12 a and 12 b are stably installed in the grooves F62 of theholder F6. Each of the grooves F62 accommodates a set of the terminals12 a and 12 b. By using a ladder structure with a height difference, theterminals 12 a of the first row and the terminals 12 b of the second roware installed on the first surface F620 and the second surface F621 ofthe groove F62, respectively. In this way, there is a vertical heightdifference (i.e., obtained by subtracting the distance h2 and thedistance h1) between each set of the terminals 12 a and 12 b, and ashort circuit caused by a contact between middle parts of the terminals12 a of the first row and the terminals 12 b of the second row can beprevented from damaging the circuit board.

In addition, the terminals 12 a and 12 b can be a pair array with roundpins or square pins, but is not limited thereto. As shown in FIG. 12,each end of each of the terminals 12 a and 12 b has a chamfer 123, andthe chamfer 123 can have any suitable shape (e.g., chamfer or round).The holder F6 has a plurality of pair of pin holes corresponding to theplurality of the terminals 12 a and 12 b, wherein the pin holes can beround holes or square holes, complementary to the shape of the pins.

In addition, the base 50 and the holder F6 of the present disclosure canbe a single, integral component, as shown in FIG. 12. The holder F6 hasa plurality of accommodation spaces (i.e., the grooves F62) for theplurality of terminals 12 a and 12 b, and the plurality of terminals 12a and 12 b have the two-row structure. One end of each of the pluralityof terminals 12 a and 12 b is connected to the rear 11, and another endof each of the plurality of terminals 12 a and 12 b is connected to theexternal substrate S. In the present embodiment, the base 50 and theholder F6 that are formed as a single component have a pair of slugholes F601 passing through the base 50 and the holder F6 that are formedas a single component, and the pair of slug holes F601 can be used toreduce a shrinkage of the base 50 and the holder F6. In addition, theholder F6 can have at least one avoiding slot F602 and at least onechamfered edge F603 on the top surface of the holder F6 adjacent to theaccommodation spaces (i.e., the grooves F62) for the plurality ofterminals 12 a and 12 b. The avoiding slot F602 is adopted foraccommodating at least one jig, and the at least one chamfered edge F603is adopted for easily disposing the plurality of terminals 12 a and 12 bin the accommodation spaces. In the present embodiment, there are twoavoiding slots F602 corresponding to each of the accommodation space andat least one pair of the chamfered edges F603 are formed on two of thetop surfaces F60 that are opposite to each other. Moreover, thechamfered edge F603 can have any suitable shape (e.g., chamfer orround). It is worth noting that the base F50 and the display unit 2 ofthe present disclosure are not limited to the above embodiments. Inanother embodiment, a groove can also be formed by an inward depressionon the bottom surface of the display unit 2, while a protrusioncorresponding to the groove can be formed by the base F50 protrudingoutward.

However, the aforementioned example is merely one of the feasibleembodiments, and is not meant to limit the scope of the presentdisclosure.
